IMPROVEMENT IN GRATES FOR FUEL-MAGAZINES.

Specification fonnirg part of Letters Patent No. 148,885, dated March24, 1874; application filed February 4, 1874.

To all whom it may concern:

Be it known that I, GEORGE S. HORN, of Scranton, in the county ofLuzerne and State of Pennsylvania, have invented certain new and usefulImprovements in Magazine or Self -Feeding Stoves, commonly known asBase-Burners; and I do hereby declare the following to be a full, clear,and exact description thereof, reference being had to the accompanyingdrawing and to the letters of reference marked thereon.

The nature of my invention consists in a grate to be applied under thelower end of the magazine of a selffeeding heating-stove, for thepurpose of retaining the coal in the magazine while the stove is beingcleaned out preparatory to building a new fire, as will be hereinaftermore fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, Iwill now proceed to describe itsconstruction and operation, referring to the annexed drawing, whichforms a part of this specification, and in which- Figure l is a sideelevation of the magazine of aself-feeding stove, with my inventionattached thereto. Fig. 2 is a plan view, and Fig. 3 a bottom View, ofthe same. Fig. 4 is a transverse vertical section, showing the means bywhich my grate is fastened.

'A represents a magazine of a self-feeding stove, constructed in any ofthe known and usual ways. The grate to be applied at the lower end ofthe magazine is composed of a series of pointed bars, B B, attached toor cast in one piece, with a curved or segmental piece, 0, from thelower edge of which the grate-bars project. From this piece 0 alsoprojects a pin, D, which enters a hole made for that purpose at thefront, near the lower end of the magazine, to hold the grate in placewhen used. When a fire goes out, it almost invariably happens that themagazine is partly, if not quite, filled with coal, and in cleaning outthe ashes, without my grate, all

fire-grate of the stove may then be dumped,

and the ashes cleaned out, the coal in the magazine being retainedtherein by the magazine-grate. The wood may then be put in, as usual, onthe firegrate, and when it becomes sufficiently ignited themagazine-grate is pulled out by means of a pair of tongs, and

the coal falls from the feeder onto the wood, and the fire is built.

This grate may be used with anysized stove or any-sized coal. If largercoal is used, the grate-bars will be made narrow, so as to be easilypushed through the coal.

I am aware that plates have been inserted through slots or openings inthe magazine, near the bottom thereof, for the same purpose sought byme. I am'also aware that false grates have been used, in connection witha fire-pot, below a magazine, held by a shoulder, which bears againstthe horizontal bar of the fire-pot, as in the case of the Patent No.128,425, of June 25, 1872. Such, therefore, I do'not claim; but

What I do claim is The supplementary grate B, provided with theattaching means or projection D, in combination with the magazine of aselffeeding stove, as specified. I

In witness that I claim the foregoing I have hereunto set my hand this13th day of January, 1874.
